Audi is one of the best names in the business when it comes to build quality. Generally speaking, Audi cars hold together well and there have been no big problems with either the A6 Allroad or the regular model.

Audi A6 Allroad reliability

The Audi A6 range was rated average for reliability in our 2017 Driver Power owner satisfaction survey of cars currently on sale in the UK. Of the owners who responded, 15.7% reported experiencing a problem with their car at least once.

Many A6 components are used elsewehere in the Audi range, and although the three diesel engines have been beefed up compared to their predecessors, there's no reason to suspect them of being unreliable. And even if you do break down, Audi supplies three years’ roadside assistance to help you get going again.

The main worry is repair costs – if something does go wrong, and the car is no longer under warranty, you could be faced with a pretty large bill. Fortunately, extended warranties are available.


The A6 is a safe car and has been awarded five out of five stars in Euro NCAP crash-testing. There are plenty of airbags to cushion you and your passengers in the event of a crash (including ones in the back of the front seats), as well as a buzzer that warns if anyone hasn’t fastened their seatbelt. The Allroad also has tyre-pressure sensors to warn of an impending puncture.

In addition to the clever electronic handbrake, one of the most useful pieces of technology is the hill-start assist system. This feature, combined with hill-descent control of the kind usually found on much larger 4x4s helps you cope with steep inclines – even in slippery conditions.

A host of safety extras can be added if you want to make your drive even safer. You can get blind-spot monitoring (which alerts you to a vehicle sitting in your blind spot with a small visual cue on the wing mirror) as well as Audi's lane-keeping assistance system, which uses gentle steering impulse to keep you between the lines on the motorway.
